The next major advance in the Web will be Web 3.0 which will be built on semantic Web technologies.

This book is intended to be a practical guide for using RDF data in information processing, linked data, and semantic web applications using both the AllegroGraph product and the Sesame open source project.

While AllegroGraph itself is written in Common Lisp, this book is primarily written for
programmers using either Java or other JVM languages like Scala, Clojure, and JRuby.
A separate edition of this book covers using AllegroGraph in Lisp applications.
